W2 Statement PDF questions

Hello,

During the upgrade to ECC lastyear, for the W2 forms, we set it as PDF and it works good. But while testing we noticed that there were some script added in SAPScript format to those W2 statment to show additional info in Employer box. This script didn't get flown to PDF forms. so we are missing the additinal info in PDF. How we make the change in PDF layout. do we need to incorporate the same code in PDF layout? does this require a java code or we could do it same way as SAPScript and do we need license to make changes in Adobe layout?. Any ideas please.

Thanks

Raj.
